and coextensive with the main body, and each groove having under-cut longitudinal edges shaped for slidable fit with the tongue-shaped couplin0 portions of the mounting bracket, so that the main body can be slidably engaged with the bracket, engaging one of the grooves in use of the main body on a left-handed door, whereas the bracket engages the other groove in use of the main body on a right-handed door, and a cover plate for covering the groove not so engaged, the cover plate having a pair of tongue-shaped coupling portions similar to those of the bracket.
These and other objects as well as characteristics of this invention will be apparent to persons skilled in the art from the study of the following description with reference to the accompanying dxawings, in which:
Figure 1 is an elevational view of the new door closer fixed to a door, a part of the door and the door frame being omitted.
Figure 2 is a perspective view of the door closer according to this invention.
Figure 3 is an exploded perspective view of the door closer.
Figure 4 is a transverse sectional view of the door closer fixed to the door.
Figure S is a transverse sectional view of a modified door closer.
Figure 6 is a transverse sectional view of another ~ -modified door closer.
As shown in Figures 1 and 4, a main body 2 of a door closer 1 according to this invention is fixed to an upper part of a~door 3 through a mounting bracket 4. Within the main body 2 of the door closer, known mechanism (not shown) is included, which performs the door closing and controls the door closing Qpeed. As the door closing mechanism, general springs (not Ahown) are suitably used, and as the controlling mechanism for the door closing speed, generally the combination of a movable piston (not shown) and oil pressure means (not shown) for controlling ~^~, ~3~
the movement of said pii3ton are ~uitably used.
A driving shaft 5 projects upwardly from an upper wall 6 of the main body of the door closer and one end of an arm 7 is fixed to the driving shaft. Another end of the anm 7 is pivoted on one end of another arm 8 by`a pin 9, another end of the arm 8 is pivoted on a bracket 10 by a pin 11, and ~he bracket 10 is connected to a stationary door frame 12. Manually opèned door 3 will be closed with desirable speed by the driving force of the driving shaft S through the arms 7 and 8 As shown in Figure 2 and Figure 3, the mounting bracket 4 is formed by an elongated rectangular plate of rectangular outline and generally rectangular cros~ i3ection, ai3 shown. The cross i3ection ha~ a pair of long tongue-shaped male ` coupling portions or projections 14 each coexten~ively extending, `
., ` ai3 ~hown, along one of it~ longitudinal upper and lower edges, these projections accordingly are mutually parallel, and extend -horizontally and t-he bracket is fixed to the door 3 by screws 16 pas~ing through holes 15 in the mounting bracket. ~ ;
: ~
The door closer main body 2 is formed by an elongated rectangular parallelepiped, as shown in Figure 2 and Figure 3, . . .
and has mutually parallel elongate walls shown as front wall 17 ~
and rear wall 18, each of these walls is provided with a groove- - -shaped, undercut female coupling portion or recess 19 and 20 each parallel to the other, each coextensively extending, as shown, alQng one of the walls 17, 18 and being, accordingly, Y~ elongated`ip the horizontal direction. Into the female coupling portion 20 of the rear wall 18 of the main body 2, the mal~ CQUp-2 ling portion 14 ofithe mounting bracket 4 i~ inserted to connect the mounting bracket and the main body mutually, and into the ' 30 female coupling portion 19 of the front wall 17, a male coupling portion 25 of a rectangular covering plate 21 i~ inserted to con-J nect the covering ~late,with the mainbody. Both of the female ....
.~ .... . .
coupling portions 19, 20 are of the same shape and -~ize, and the male coupling portions 14 and 25 of the mounting bracket 4 and of the covering plate 21 may be inserted into either of the female coupling portions 19 and 20. As also shown,- both of the female coupling portions 19 and 20 are arranged symmetrically with respect to the vertical central plane of the main body 2.
Therefore, in case of the door 3 being left-handed, as ~hown, the male coupling portion 14 of the mounting bracket 4 is inserted into the female coupling portion 20 and the male .
coupling portion 25 of the covering plate 21 into the female coupling portion 19: but it will be understood that in case of the door 3 being right-handed, the male coupling portion 14 of the mounting bracket 4 is inserted into the female coupling portion 19 and the male coupling portion 25 of the covering plate 21 into the female coupling portion 20. Thu~, by selec-tively inQerting the coupling portions 14 and 25 of the mounting `~ bracket ana the covering plate into the female coupling portions 19 and 20, the same door closer may be fixed selectively to a left-handed or riqht-handed door, and the top wall 6 of main body 2 of the closer is always located at the upper position, that i3 the main body need not be reversed as to its top and bottom. Thus, the structure of the door closer is simple and : compact.
Since the light and handy mounting bracket 4 is fixed to the door by screws and then the closer is fixed to the door by slidably engaging the female coupling portion 19 or 20 of the cloQer main body 2 with the male coupling portion 14 of the mounting bracket 4, the mounting operation thereof may be effected ~; easily and promptly. When the closer is fixed to the door, fix~
ing screws 16 for the mounting bracket are hold down by the -bot- -tom of female coupling portion 19 or 20 of the main body 2, so that the screws will never, become loose. The fixing of the .
closer i~ favorably maintained and has good appearanceJ the screws being invisible from outside.
In order to slidably engage the male coupling por-tions 14 and 25 of the mounting bracket 4 and the covering plate 21 with the female coupling portions 19 and 20 of the main body of the closer, each of the female coupling portions 19 and 20 i9 undercut by having a pair of confronting inner wall face~ 23 or 24 forming a dovetail groove as shown in Fig. 4, and these inner wall faces 23 or 24 are mutually parallel extending in the horizontal direction as well as inclined so as to decrease the spacing between inner wall faces 23 or 24 as these faces advance towards the opening face of the groove. Also, the mounting bracket 4 and the covering plate 21 have substantially equal sectional shape to those of grooves 19' and 20'. Each of the male coupling portions 14 and the male coupling portions 25 of upper and lower edge-portions of both plate 4 and 21 is mutually parallel extending in the horizontal direction and inclined so a~ to engage with the inner wall faces 23 and 24. ~he dimensions of thickness of the mounting bracket 4 and those of depth of ,'~ 20 grooveR 19' and 20' of the main body 2 are substantially equal,and when the main body 2 i9 fixed to the wall face of door 3 through the mounting bracket 4, the rear face 18 of the main body -contacts with the wall face of the door to hide the mounting ~ --bracket-4, thereby the closer is fixed with good appearance.
~he male coupling portions 14 of the mounting bracket ~ 4 and the female coupling portion 19 or 20 of the main body 2 `~ are merely engaged relatively to allow relative sliding of bothof the portions. The sliding between these portions 14 and 19 or 20 is prevented by inserting a screw 22 into a through hole ' 30 26 of the main body 2 and by screwing it into a screw hole 27 of the mount~ng bracXet 4. To keep a head 28 of the 5Grew 22 not to protrude outside from the bottom face of the gro~e l9' Q,r ' ~0667Z8 20', for instance, the head is formed as a flush head, and a bottom face 29 iA formed conically to receive the flush head.
Since the head 28 of the screw is held down by the cover~ng plate 21, looseness of the screw 22 is prevented, and since the covering plate cover~ the groove 19' or 20', the head of fixing ~crew 22 and the groove axe hidden to keep the appearance of front facQ of the main body good. The covering plate 21 may be colored and patterned in various manners, and by using this covering plate, the front face of the door closer may be made colorful and beautiful. The covering plate may be made of metal, preferably it is formed by ~ynthetic resin to facilitate the decoration of the covering plate. Further, relative sliding between the covering plate 21 and the groove 19' or 20' of the main body 2 may be prevented by tight fitting of the covering plate 21 in the groove 19' or 20' of the main body, but it may be more strongly prevented by fitting a projected portion 30 provided oh the rear face of the covering platè into a recess or indentation31 provided on the bottom face of the groove 19 ~` or 20'.
The mounting bracket 4 may be modified as shown in Fig. 5. The modified mounting bracket 4a ha~ fla~ges 32 which extends upward and downward from ends of inclined male coupling portion 14a, with which flanges 32 the rear face 18 or front face , 17 of tXe main body 2 contacts. The mutually contacting faces - of the mounting bracket 4a and the main body 2 are more easily and exactly formed than the corresponding face~ of the door 3 and the main body 2.
In Fig. 6, there is ~hown a further modified coupling portion of a mounting bracket 4b, a covering plate 21b and a main body 2b. The mounting bracket 4b and the covering plate 21b have ~-shaped male coupling portion~ 14b and 25b extending upward and downward from side faces thereof. A female coupling ~066'7Z8 portion l9b, 20b of the main body ha~ a T-grooved shape having extended portion~ 23b and 24b extending from opening edge~ in confronting direction. Between the extended portions 23b and 24b and the bottom of groov~s, tongue-shaped male coupling por-tions 14b and 25b of the mounting bracket and the covering plate are fitted to connect with each other.
It is to be understood that the present invention i~ not limited to the above mentioned embodiment thereof, but may be otherwise variously modified within the ~cope of the following claimq.

As shown in Figures 1 and 4, a main body 2 of a door closer 1 according to this invention is fixed to an upper part of a~door 3 through a mounting bracket 4. Within the main body 2 of the door closer, known mechanism (not shown) is included, which performs the door closing and controls the door closing Qpeed.

A driving shaft 5 projects upwardly from an upper wall 6 of the main body of the door closer and one end of an arm 7 is fixed to the driving shaft. Another end of the anm 7 is pivoted on one end of another arm 8 by`a pin 9, another end of the arm 8 is pivoted on a bracket 10 by a pin 11, and ~he bracket 10 is connected to a stationary door frame 12. Manually opèned door 3 will be closed with desirable speed by the driving force of the driving shaft S through the arms 7 and 8 As shown in Figure 2 and Figure 3, the mounting bracket 4 is formed by an elongated rectangular plate of rectangular outline and generally rectangular cros~ i3ection, ai3 shown. The cross i3ection ha~ a pair of long tongue-shaped male ` coupling portions or projections 14 each coexten~ively extending, `

The door closer main body 2 is formed by an elongated rectangular parallelepiped, as shown in Figure 2 and Figure 3, . . .
and has mutually parallel elongate walls shown as front wall 17 ~
and rear wall 18, each of these walls is provided with a groove- - -shaped, undercut female coupling portion or recess 19 and 20 each parallel to the other, each coextensively extending, as shown, alQng one of the walls 17, 18 and being, accordingly, Y~ elongated`ip the horizontal direction. Into the female coupling portion 20 of the rear wall 18 of the main body 2, the mal~ CQUp-2 ling portion 14 ofithe mounting bracket 4 i~ inserted to connect the mounting bracket and the main body mutually, and into the ' 30 female coupling portion 19 of the front wall 17, a male coupling portion 25 of a rectangular covering plate 21 i~ inserted to con-J nect the covering ~late,with the mainbody.

coupling portions 19, 20 are of the same shape and -~ize, and the male coupling portions 14 and 25 of the mounting bracket 4 and of the covering plate 21 may be inserted into either of the female coupling portions 19 and 20. As also shown,- both of the female coupling portions 19 and 20 are arranged symmetrically with respect to the vertical central plane of the main body 2.
Therefore, in case of the door 3 being left-handed, as ~hown, the male coupling portion 14 of the mounting bracket 4 is inserted into the female coupling portion 20 and the male .
coupling portion 25 of the covering plate 21 into the female coupling portion 19: but it will be understood that in case of the door 3 being right-handed, the male coupling portion 14 of the mounting bracket 4 is inserted into the female coupling portion 19 and the male coupling portion 25 of the covering plate 21 into the female coupling portion 20. Thu~, by selec-tively inQerting the coupling portions 14 and 25 of the mounting `~ bracket ana the covering plate into the female coupling portions 19 and 20, the same door closer may be fixed selectively to a left-handed or riqht-handed door, and the top wall 6 of main body 2 of the closer is always located at the upper position, that i3 the main body need not be reversed as to its top and bottom. Thus, the structure of the door closer is simple and : compact.
Since the light and handy mounting bracket 4 is fixed to the door by screws and then the closer is fixed to the door by slidably engaging the female coupling portion 19 or 20 of the cloQer main body 2 with the male coupling portion 14 of the mounting bracket 4, the mounting operation thereof may be effected ~; easily and promptly. When the closer is fixed to the door, fix~

closer i~ favorably maintained and has good appearanceJ the screws being invisible from outside.
In order to slidably engage the male coupling por-tions 14 and 25 of the mounting bracket 4 and the covering plate 21 with the female coupling portions 19 and 20 of the main body of the closer, each of the female coupling portions 19 and 20 i9 undercut by having a pair of confronting inner wall face~ 23 or 24 forming a dovetail groove as shown in Fig. 4, and these inner wall faces 23 or 24 are mutually parallel extending in the horizontal direction as well as inclined so as to decrease the spacing between inner wall faces 23 or 24 as these faces advance towards the opening face of the groove.
